The present invention relates to a method for melt-proofing synthetic fibers. Conventional methods for melt-proofing synthetic fibers include the method described in Japanese Patent Publication No. 12479/1983, in which a mixed aqueous solution of a melamine derivative compound and an inorganic acid, an organic acid, or a salt thereof is applied and then heat-treated in the presence of moisture; The method described in Japanese Patent Publication No. 49-32760, in which an anionic surfactant is added to the mixed aqueous solution, or an aqueous solution containing a melamine derivative compound, a nonionic surfactant, and propane sultone or tetrakis hydroxymethylphosphonium chloride. A method described in JP-A-50-136500, in which a steam treatment is performed after deposition, is known. Although the fibers obtained by these methods have melt-proofing properties, the dyed fibers, especially those dyed by the adhesion of melamine resin, cause a so-called whitening phenomenon, lack clearness of color tone, and significantly reduce their value as products. In addition, especially when the amount of adhesion is small, these catalysts have poor washing resistance, and depending on the type of catalyst, many of them lack stability in aqueous solutions, resulting in poor operability. The present inventors have completed the present invention as a result of intensive research to eliminate such drawbacks and develop synthetic fibers with excellent melt resistance. An object of the present invention is to provide a fusible synthetic fiber that is free from the so-called whitening phenomenon, has a clear color tone, and has wash resistance. Another object of the present invention is to provide a processing method for manufacturing synthetic fibers having such excellent melt resistance in an industrially easy and inexpensive manner without causing problems in stability and the like. The method of the present invention is characterized by applying an aqueous solution containing a melamine derivative compound, a salt of polyacrylic acid, and an inorganic acid salt catalyst to synthetic fibers, and then subjecting the fibers to a moist heat treatment. Synthetic fibers applicable to the present invention include polyester fibers, polyamide fibers, polyacrylonitrile fibers, polyolefin fibers, etc., and these can be used in any form such as cotton, yarn, woven or knitted fabrics, or nonwoven fabrics. In addition, these synthetic fibers can be blended with each other or with non-heat-melting fibers such as natural fibers,
It can also be used in mixed weaving or mixed knitting. Melamine derivative compounds applicable to the present invention include commonly known melamine derivatives, such as hexamethylolmelamine, trimethylolmelamine, trismethoxymethylolmelamine,
Examples include methylol derivatives such as hexakismethoxymethylolmelamine. Among these, hexamethylolmelamine and trimethylolmelamine are preferred. The polyacrylic acid salt applicable to the present invention is a water-soluble salt of polyacrylic acid or polymethacrylic acid, and includes an alkali metal salt and an ammonium salt. The polyacrylic acid may be not only linear but also cross-linked and branched.
Regarding the degree of polymerization of polyacrylic acid, for example, one having a solid content of 40% and a viscosity of 20,000 cps or less, preferably 1,000 cps or less is easy to use, but it is not limited to this. Among the polyacrylic acid salts, alkali metal salts are particularly preferred from the viewpoint of anti-melting effect and washing resistance. Inorganic acid salts applicable to the present invention include metal salts such as sodium, magnesium, aluminum, zinc, etc. or ammonium salts of inorganic acids such as sulfuric acid, persulfuric acid, hydrochloric acid, phosphoric acid, and nitric acid; Ammonium persulfate salts are particularly preferred from the viewpoint of ease of handling. In the method of the present invention, a melamine derivative compound,
Polyacrylic acid salts and inorganic acid salts are applied to synthetic fibers as aqueous solutions. The concentration of the melamine derivative compound in the aqueous solution depends on the desired texture of the fiber, processing conditions, or the type and concentration of polyacrylic acid.
Although it varies depending on the type of catalyst, concentration, etc., it is usually 5.
-15% by weight, preferably 6-12% by weight. Although the concentration of the polyacrylic acid salt also varies depending on the above-mentioned conditions, it is usually 0.5 to 5% by weight, preferably 1 to 3% by weight. The inorganic acid salt catalyst is usually used in an amount of about 0.1 to 5% by weight. The polyacrylic acid salt is usually used in an amount of 5 to 40 parts by weight, preferably 10 to 35 parts by weight, per 100 parts by weight of the melamine derivative compound in the aqueous solution. In addition, it is very easy to use the aqueous solution at room temperature in terms of operation. A surfactant may be added to the aqueous solution of the melamine derivative compound of the present invention. As the surfactant, anionic surfactants are particularly preferred. The anionic surfactant promotes the formation of a film formed by the melamine derivative compound and the salt of polyacrylic acid, and a nonionic surfactant may be used in combination to promote permeability. Anionic surfactants include:
Soap, carboxylic acid anion activator of sarcosinate, higher alcohol sulfate ester salt, sulfated oil, sulfated fatty acid ester, sulfated olefin,
sulfate salt-based anion activators such as sulfate ester salts, sulfonate-based anion activators such as alkylbenzene sulfonates, alkylnaphthalene sulfonates, and lignin sulfonates, higher alcohol phosphate ester salts, and phosphate ester salt-based anions. Examples include activators. These surfactants are usually 0.01
It is used in a range of 1% by weight. An aqueous solution containing a melamine derivative compound or the like can be applied to synthetic fibers by an appropriate method such as a pad method, a dipping method, a spraying method, or a coating method. The synthetic fibers to which a melamine derivative compound or the like has been added are then subjected to a moist heat treatment without drying. Humid heat treatment is usually performed using steam heat. Moist heat treatment is usually at a temperature of 60-180℃, preferably
The temperature is 95°C to 180°C, and the processing time varies depending on the processing temperature, but is usually about 3 to 180 minutes. Next, soaping, washing with water, dry finishing, etc. are carried out in accordance with conventional methods to obtain the final product. If necessary, oil and water repellent treatment with fluorine resin, water repellent treatment with silicone resin, etc. can be applied during the final finishing. , other processing agent processing such as charging processing may be performed. As described above, according to the method of the present invention, it is possible to obtain synthetic fiber products that do not cause dullness of hue, have excellent melt resistance and washing resistance, and also do not have hardening of texture due to processing. It is soft. Hereinafter, the present invention will be explained in detail with reference to Examples. In the examples, the resin adhesion rate (%) was calculated from the weight increase of the treated cloth, and the hue change was expressed as the color difference ΔE between the treated cloth and the untreated cloth when measured by a spectrophotometer. or,
Melting resistance was evaluated by a glass bulb test and a tobacco contact test under the following conditions. ΓGlass Ball Test A hollow glass sphere weighing 1.5g and having a diameter of 1.5cm is placed in a crucible with a diameter of 3cm and heated in an electric furnace. When the crucible has been heated to a predetermined temperature, the whole crucible is taken out and the glass bulb is dropped onto a cloth. The porosity is determined by the minimum heating temperature required for the hollow glass sphere to melt the cloth and fall downward.It is indicated by the minimum temperature at which the glass sphere falls. Γ Cigarette contact test: Hold a lit cigarette vertically against a cloth under its own weight for 30 minutes.
Observe the condition after contact for a second. The numbers indicate the size of the melt hole (diameter mm), and the numbers in parentheses indicate the size of the focus (mm). Furthermore, the durability of anti-melt resistance due to washing was evaluated under the same test conditions as above after 10 consecutive tests under the following conditions.
